Hi gambit277,firstly you should update you Maxon C4D to latest build, and remove the unnecessary .dylib files, leaving only c4doctane-R18.dylib file.Please, read this other discussion about R18.057 and Sierra:viewtopic.php?f=30&t=61724Then, did you enable firstly the nework slaves in Live View menu Optiom/Network rendering/Settings, or only in Render Settings?ciao beppe
